"I'm used to rivers that know what they're doing."

Matthew DiLuglio's insight:

Lol... the first words that went through my head were h--- (heck) yeah.  David Bowie... sung by an astronaut... okay, back to Geography. I thought that the rivers reminded me of something I thought of during the talk in class about lava rock being changed into other kinds of rocks over time, and cycling around.  I thought on a larger scale, about this universe, and I have read before that people are studying different areas of space-time fabrics, trying to find origins of the Universe, and answers to other existential questions.  I suppose that if one could trace patterns of rivers, and if one could trace patterns of rocks, to find where they came from, and why/how they came where they came, then by examining the (assumedly tattered and marked) fabrics of space and time, people would be able to determine origins of everything from the beginning of what existed before all universes, and also the origins of life forms.  I enjoyed the movie Prometheus, which was directed by Sir Ridley Scott, and I had to say that I thought that the messages found on rocks in caves, as a catalyst that lead the cast to go visit an alien world that had something to do with human origins, could be very literally taken.  If there are clues in rocks, why wouldn't there be other clues, possibly in celluar components of life forms, or space and time?  Applying the idea of studying rocks and rivers and other physical geographical pursuits to the idea of applying it on a gigantic scale greatly appeals to me.  I believe that humans will find some answers that way, but I hadn't directly realized just that until we mentioned some stuff about physical geography, and glacial forces carrying and spreading out rocks, and deposits and erosion.  After all, the Milky Way has origins, so why believe that we came from the Milky Way, rather than beyond?

When I first loooked at this picture I thought it was a piece of art. Its amazing has geography can look so beautiful and natural at the same time.

hmm, looks like some river had a little to much

All rivers move. Those that have a wide, flat basin meander most. Those meanders can be even more dramatic than in this image, snaking 10's of kilometres sideways over time. Combine this action with geological upheaval and it gets even more interesting. Check out images of the Murray River in Australia from space.

Population 7 Billion

Population 7 Billion | Matt's Geography Portfolio | Scoop.it

"Just 200 years ago, there were only 1 billion people on the planet, and over the next 150 years, that number grew to 3 billion. But in the past 50 years, the global population has more than doubled, and the UN projects that it could possibly grow to 15 billion by the year 2100. As the international organization points out, this increasing rate of change brings with it enormous challenges."

Matthew DiLuglio's insight:

Population growth seems to be a trend that we see happening now as sharply increasing, but it is supposed to level out.  I doubt that this will happen.  Realistically, there are correllations between colonizations of other countries and population growths.  We are at a time when people are signing up to start colonies on Mars, and inevitably, other worlds.  Compared to the tiny confines of Earth, the large universe waits for us with open arms and trillions (potentially even infinite times) the quantities of living space.  Perhaps the leap in population comes at a time when we will be colonizing other worlds.  If Earth in the now can hold 7 billion people, and it is expected to level out under double that, that means another Earth-sized plane would be able to hold the same number as Earth, assuming all needs can be met (food, water, etc).  Earth is becoming one of the homeworlds of one of the dreaded species seen in movies, like Aliens, that spreads like an infection.  The multiplying on the homeworld has been seen as abundant, but speculation of the future is even more scary.  I would guess that DNA modification would take place in the relatively near future to protect colonists from the wrath of raw space and mishaps that may befall them on the colonies, as well as eliminate a few of the needs of humans- oxygen, food, water- to make the available living space more suitable for them.  Look at it like a bucket of rainwater filling up in the rain- at full capacity, there is no other option if the rain keeps falling; it begins to overflow.  My speculation is based on where there is available land for colonizing, and it seems that we humans might move to nearby, and eventually, more distant worlds, instead of trying to overpopulate Earth.

At first, the world's population did not grow a lot. Now we are growing about 1 billion in 12 years, that is scary compared to the 200 years we grew about 1 billion. These are some pictures of some highly dense populations. It is even scarier that in 2100 the population is suspected to be 15 billion.

jada_chace's curator insight, September 10, 2014 9:25 AM

Over the years our world population has grown enormously. Almost  200 years ago there was only 1 billion people in the world, and as time went on the population started to increase dramatically. By 2100, geographers say the population will grow to be 150 million people in the world. The population continues to grow throughout time, we therefore should be cautious on how we are to our environment.

Robert Hardy Simpkins's curator insight, September 10, 2014 9:29 AM

The fact that in just 86 years we will have 15 billion people in our world is a very scary thought.will we have enough resources to account for all the people on Earth. Will there be multiple diseases killing people off. Our population needs to be controlled.
